[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1, referring to Figures 1-4 This is the first embodiment of the present invention, which provides a marine combined adaptive electromagnetic lifting device, comprising: A rectangular frame 1 has a movable guide rail interface at the top, a first rectangular plate 3 at the bottom of the rectangular frame 1, an iron chain 7 on one side of the first rectangular plate 3, and a first electromagnet 5 fixedly connected to the end of the iron chain 7. The second rectangular plate 4 is set at the top of the rectangular frame 1, and the second electromagnets 6 are suspended on both sides of the second rectangular plate 4 by iron chains 7. Infrared sensor 14 and stress / displacement sensor 15 are integrated on the second electromagnet 6; The central control module is used to receive sensor data and control the angle adjustment of the second electromagnet 6. A current control unit 10 for controlling the on / off state of the first electromagnet 5 and the second electromagnet 6, and an upper and lower guide rail system 2 for guiding the translational movement of the first rectangular plate 3 and the second rectangular plate 4. The iron chain 7 is fixedly installed on the surface of the first rectangular plate 3 and the second rectangular plate 4 by the first fixing bolt 11; Furthermore, the upper and lower guide rail system 2 includes a translation drive and positioning mechanism 17, which also includes a ball screw transmission mechanism driven by a servo motor. It should be noted that by precisely controlling the rotational motion of the ball screw through a servo motor, the rotation is converted into linear displacement, thereby achieving high-precision translation and positioning of the first rectangular plate 3 and the second rectangular plate 4. Compared with traditional hydraulic or pneumatic methods, the ball screw has advantages such as fast response speed, high repeatability, and stable operation. It can effectively improve the operational flexibility and control precision of the hoisting device in complex spatial environments and is suitable for high-precision shipbuilding and maintenance scenarios.

[0030] Furthermore, the second electromagnet 6 is connected by a hinge to achieve angle adjustment, the infrared sensor 14 is a linear scan infrared detector, the first electromagnet 5 is provided with a first chain hanging interface 8 at the connection point with the iron chain 7, the second electromagnet 6 is provided with a second chain hanging interface 12 at the connection point with the iron chain 7, and the surfaces of the first electromagnet 5 and the second electromagnet 6 are provided with an electromagnet shell 9. It should be noted that the above structural design enables the second electromagnet 6 to automatically adjust its angle according to the curvature of the steel plate surface during adsorption, improving the fit and adsorption stability. The linear array scanning infrared sensor 14 can scan the contour of the steel plate surface in real time, providing high-resolution spatial data for AI algorithm analysis. The first chain-hanging interface 8 and the second chain-hanging interface 12 adopt a modular connection design, which facilitates the quick replacement of electromagnet components of different specifications, enhancing the applicability of the equipment. The electromagnet housing 9 serves to prevent dust and water damage, protect the internal coils and circuits, and improve overall durability and safety.

[0031] Furthermore, the current control unit 10 is used to independently control the start and stop of the first electromagnet 5 and the second electromagnet 6, and supports three control modes: global adsorption, regional adsorption and gradual release. It should be noted that this design allows for flexible selection of adsorption modes based on different steel plate shapes, weight distributions, and operational requirements. Full-area adsorption is suitable for large-area flat steel plates, ensuring maximum adsorption force; regional adsorption can apply adsorption force to local areas, suitable for irregularly shaped or thin plate materials; and the gradual release mode can disconnect power in stages during unloading to avoid the risk of impact or slippage caused by instantaneous demagnetization. The multi-mode control strategy improves the safety, adaptability, and energy efficiency of the hoisting process.

[0032] Furthermore, a buffer damping component is provided between the second electromagnet 6 and the second rectangular plate 4 to alleviate the impact load during the adsorption or release of the steel plate. It should be noted that the buffer damping component is usually composed of a spring-hydraulic composite structure or a rubber shock-absorbing pad. It absorbs part of the kinetic energy at the moment the electromagnet contacts the steel plate, reducing the mechanical stress and vibration transmission caused by rigid collision. This not only extends the service life of the equipment, but also reduces the risk of the steel plate shifting or falling off due to sudden force changes during hoisting. It is especially suitable for high-frequency, large-tonnage hoisting tasks, improving the stability of the whole machine operation and the safety of operators.

[0033] This embodiment also provides a control system for a marine combined adaptive electromagnetic lifting device, including: A sensor data acquisition unit for receiving data from infrared sensor 14 and stress / displacement sensor 15; The electromagnetic module unit 13, which is located inside the first electromagnet 5 and the second electromagnet 6, contains a coil, a driving circuit and an adjustable adsorption structure. An AI adaptive algorithm module used to analyze sensor data and generate control commands; A current control unit 10 for performing on / off control of the first electromagnet 5 and the second electromagnet 6; Translation control unit for controlling the movement of translation drive and positioning mechanism 17; A second fixing bolt 16 is provided at the connection between the infrared sensor 14 and the stress / displacement sensor 15 and the first electromagnet 5 and the second electromagnet 6. Furthermore, the sensor data acquisition unit is used to read data from the infrared sensor 14 and stress / displacement sensor 15 integrated on the second electromagnet 6 to obtain the deformation profile and stress condition of the steel plate surface. The current control unit 10 is used to monitor the working status of the first electromagnet 5 and the second electromagnet 6, and to record the adsorption current intensity and working time parameters of each magnet. Data is uploaded to a remote server via an IoT communication module to form a historical database; The data collected from the sensors and current control unit is filtered to remove outliers and noise interference; The preprocessed data is then normalized using the following expression: ; in, Represents the original data. This represents the average value. Indicates standard deviation; Design a neural network structure, including an input layer, hidden layers, and an output layer; The input layer receives preprocessed sensor data, and the output layer predicts the optimal magnet activation sequence and angle adjustment path. The backpropagation algorithm (BP) is used to train the neural network model, and the value of the loss function is minimized by adjusting the weight matrix and bias terms. Among them, the loss function The expression is: ; in, It is the actual value. It is a predicted value; The dataset is divided into a training set and a validation set. The model is trained using the training set and its performance is tested on the validation set. Based on historical hoisting data, the model's decision-making strategy is further optimized using a reinforcement learning mechanism. By simulating different hoisting scenarios, the reward value under each strategy is calculated, and the strategy that maximizes the cumulative reward is selected as the final strategy. When a new hoisting task begins, the central control module calls the optimized neural network model, inputs the current state information of the steel plate, and obtains the optimal magnet activation sequence and angle adjustment path.

[0034] The translation control unit and translation drive and positioning mechanism 17 are used to adjust the positions of the first rectangular plate 3 and the second rectangular plate 4 according to the model output results. At the same time, the start and stop of each group of electromagnets are controlled by the current control unit 10.

[0035] Throughout the hoisting process, sensor feedback data is continuously monitored, and the angle and position of the magnets are dynamically adjusted according to the actual situation to ensure the best adsorption effect. It should be noted that the control system, by constructing a closed-loop feedback mechanism, inputs the data from the infrared sensor 14 and the stress / displacement sensor 15 to the AI ​​adaptive algorithm module. Combined with the neural network learning model, it realizes intelligent recognition of the steel plate morphological characteristics and dynamic optimization of the adsorption path. The backpropagation algorithm (BP) and reinforcement learning mechanism enable the system to have self-learning capabilities, continuously accumulate historical data and optimize decision-making strategies, thereby outputting the optimal magnet activation sequence and angle parameters when facing different working conditions, significantly improving the degree of automation and hoisting success rate.

[0036] Furthermore, the control system includes an IoT communication module that supports breakpoint resume and remote maintenance functions, and can upload device status and fault logs in real time. The specific steps are as follows: The sensor data acquisition unit collects the working status of the first electromagnet 5 and the second electromagnet 6, the data of the infrared sensor 14 and the stress / displacement sensor 15, and the status information of the current control unit 10. The data is encapsulated into data packets according to a predefined format, where each data packet contains a device identifier, timestamp, data type, and specific value; The IoT communication module sends encapsulated data packets to the remote monitoring platform in real time. With the built-in breakpoint resume mechanism, when the upload fails due to network interruption or other failures, the unsuccessfully uploaded data packets are automatically saved and the upload continues after the network is restored. After each successful data packet upload, update the local record and mark it as uploaded to avoid uploading the same data repeatedly. When an anomaly or equipment failure is detected, the central control module generates a detailed fault report, including the time and location of the fault, possible causes and the scope of its impact. The generated fault reports are also packaged into data packets of a specific format and uploaded to the remote monitoring platform in a timely manner via the IoT communication module; The remote access interface provided by the IoT communication module allows technicians to perform diagnostics and maintenance operations on the equipment via the Internet; It should be noted that the introduction of the IoT communication module enables this system to have remote monitoring and maintenance capabilities. Even in the event of a network interruption, data integrity can be ensured through a breakpoint resume mechanism. All device status information, fault logs, and operation records can be uploaded to a remote server in real time, facilitating centralized management and big data analysis. At the same time, the remote access interface supports online debugging, firmware upgrades, and troubleshooting, significantly reducing on-site maintenance costs and time expenditures. This makes it particularly suitable for special operating environments such as offshore platforms and ocean-going vessels where frequent personnel deployment for maintenance is difficult.

The control system for the marine combined adaptive electromagnetic lifting device as described in claim 4, characterized in that: A buffer damping assembly is provided between the second electromagnet (6) and the second rectangular plate (4) to alleviate the impact load during the adsorption or release of the steel plate.

6. The control system for the marine combined adaptive electromagnetic lifting device as described in claim 1, characterized in that: The control system includes an IoT communication module that supports breakpoint resume and remote maintenance functions, and can upload device status and fault logs in real time. The specific steps are as follows: The sensor data acquisition unit collects the working status of the first electromagnet (5) and the second electromagnet (6), the data of the infrared sensor (14), the stress and displacement sensor (15), and the status information of the current control unit (10). The data is encapsulated into data packets according to a predefined format, where each data packet contains a device identifier, timestamp, data type, and specific value; The IoT communication module sends encapsulated data packets to the remote monitoring platform in real time. With the built-in breakpoint resume mechanism, when the upload fails due to network interruption or other failures, the unsuccessfully uploaded data packets are automatically saved and the upload continues after the network is restored. After each successful data packet upload, update the local record and mark it as uploaded to avoid uploading the same data repeatedly. When a device malfunction is detected, a detailed malfunction report is generated using the central control module, including the time and location of the malfunction, possible causes, and the scope of its impact. The generated fault reports are also packaged into data packets of a specific format and uploaded to the remote monitoring platform in a timely manner via the IoT communication module; The remote access interface provided by the IoT communication module allows technicians to perform diagnostics and maintenance operations on the equipment via the Internet.
